I recently purchased SiN from best buy (hoorah for rip offs) and a brand new DVD-ROM drive (Sony). However, when I try to play the game, the graphics get extremely jerky and the game slows down right after the first cut scene (when you are running through the hallway). Im not sure what is going on, I have a 2.8ghz P4 CPU, GeForce 6600gt gfx card. I know both items work properly, I am afraid that the DVD player may be damaged some how to cause the game to slow down like that and become jerky as it does.
To put it into perspective, it is almost like I dont have enough CPU to play the game, like my computer is slowing down because the CPU is working to hard. My CPU's average temperature is around 80-100 degrees fahrenheit, in that range, and I know it can handle way more before it automatically slows, but it is just strange.
Also, when I move the mouse in the opening screen (to select new game, load game, etc.) The mouse gets starts to flash, and blinks periodically, mainly as I move it.

Its a paragraph, unnecessary to use enter. (But did so to placate you and the other users).
Anyhow, I had posted my dxdiag information, it was in an edit because I originally forgot it. (It's the link at the end of the post).

Not really, that is during gaming mode. At normality (as it is right now) it is about 26C, so about ~78F. My room temperature is about 75-ish.

Also, for some reason, whenever I try to watch some of the small videos I have on my computer (around 1m) my computer slows WAY down. I mean extremely down. When I move my house, it flashes in one spot then in another about 1/2 a second later, then in another at the same time interval. This happens on any media player, whether windows or not. If I end the player, the computers refresh rate is still EXTREMELY slow. To the point I cannot do anything at all but turn off then turn back on.

Yeah, I have. Ill try to reinstall it though.
ACTUALLY, I installed the drivers that came from the motherboard, Ill see if that will work.

Would that have any affect on why my videos will not work either?

<ee>
I have just installed the latest VIA hyperion 4-1 and my video media files still do not work for some ungodly reason. I think that the vmf thing may be tied into the same problem that is affecting SiN.
I should also mention that the sound stutters horrifically when I enter that first action scene (as does the video), and this isnt the only game it does it on. It does the same thing on Hitman Blood Money. I had never played either of these games on my computer before I installed the new mobo, but now that I have, the graphics became a whole lot crappier, my media files will not work (video only), and I am at a loss.
